CHARLES N. ARMFIELD, OF GUTHRIE CENTER, IOWA;

AXLE-CELEB.

application filed April 23, 1912. Serial No. 692,727.

Be it known that I, centres. AnnirrsLo, a citizen of the United States, residing at Guthrie Center, in the county of To all whomit may concern:

'Guthrie and State of Iowa, have invented a new and useful A'xle-()iler, otwhich the following is a specification. I

The object ofmy invention to provide an axle oiler of simple, durableand ineifipem' sive constrfiction, which is I peculiarly adapted to -he used with a Wagon, which oiler includes a grease cup, adapted to be where it will not be interfered with by the in the construction, arrangenientand comhination of the various part sol my device,-

whereby the objects contemplated arez'attain'ed, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which Figure -1 shows a top or plan ie w of a vwagon axle, having installed thereon, an

axle oiler embodying my invention Fig. 2 shows a side elevation of the same, part of the axle and the skein thereon being shown in section. Fig. 3 shows a central, vertical, longitudinal, sectional View through 'the grease cup. Fig. 4-shows an end viewof' the grease cup, with the cap removed;

In the accompanying drawings, I have used the reference numeral 10 to indicate generally, a wagon axle, on the end of which 3 is. a, tapcred portion 11 and above which is asand boa rd 1:2. Mounted on the tapered portion 11 is slrein 13, which is. preferably Isa made with a longitudinal groove 15 'in its upper surface ainrhwith an opening 16 extending from the upper or inner end of said groove through a portion of the skein to the inner end thereof, on its upper side. The

upperror inner end of the hole or opening 16 is slightly enlarged or reamed out, as shown in Fig. 2. y

For containing grease, I provide cup 17. preferably made in the form sofa hollow cylinder, closed at one" end, [and Specification of Letters Patent.

a grease Patented May 91', 1316,

open at the other. At its closed end,,the.-

grease cup 17 is provided with a: base18' eX-:= I tending laterally from the cup, ;Onthe lower part of the grease cup is an outwardly. extending, externally screwthreaded, eylins drical projection 19 through which extends;

an opening 20 communicating with the intenor of the grease cup. 1n the base 18 are openings 21. The grease cu'p isse'curedt0 the axle by bolts 22 or other suitable'means extended through the openings 21 and secured to the axle 10.

The interior of the grease cup 17 is' screwthreaded, as shown i'n'Fig. 3 and.

mounted therein, is an externally screwthreaded plug 2 1. At the open end of the cup 17 is formed a circumferential, annular, outwardlyvextending rib'25. Mounted on the cup 17 is a detachable cap or. cover 26 provided with a pluralityof spring clips- 27 designed to yieldingly engage the rib 25.

On the inner surface of the cap 26,-is an v angular stem 28 extending to position near the bottom of the grease cup and slidably. but non-rotatably mounted in the plug 2 1.,

On the-upper or outer surface of the plug 24 is a washer 29, above which is a second washer 30. The washers 29 and 30 are secured to the plug 24 by screws 31 or other suitable means. T he washers 29 andBO are provided with a central opening, designed to f'isnugly or slid-ably receive the stem 28. For conducting greasc from the grcaw cup to the hole 16 and the groove 15, I

provide a tube it one end of whichis' an angular'flange 33 which is placed adjacent to the extension 1-9 and is held in such a position by a screw cap 3 1. The outer endof the tube 32 is received in the enlarged end of the hole 16 and the tube 32 is secured in bracket 35.

In the practical installed on the and the plug are removed from the grease its position by means of use of my improved axle 01101, the grease cup and tube 32 'are The detachable top cup which is then filled with grease. "They plug is screwed in and the cap is placed '11! position. After running a vehicle a certain length of time the cap may .be rotated and. the grease thereby forced through the tube 32 to the skein. My axle oilerhasthe advantage of rotating the grease cup at. a point where it is not interfered with by the sand board or other partsof the wagon and.

where articles dropped from the-wagon cannot injure the imp. Thegrease in the cup 'may be forced to the skein without removthe top of the cup. The user can tell when the rise is exhausted in the cup on account o t he fact that the cap cgnnot be rotated when the of the cup.

I claim as my invention:

In an oiling device comprising a cylindrial grease cup internallyscrew-threaded plug reaches the bottom having an open and a closed end,' and 'provided with a passage at its closedend, a screw-threaded plunger mounted in the interior of said grease .cup, said plunger being provided with an angular central opening, a cap' mounted-on said clip, the

cup and (Bap being provided'with coasting means for rotatably mounting the cap on the cup, and to prevent the removal. of the cap from the cup, an angular shaft mounted on the cap extended through the opening in the plunger, a washer on the side of said plunger adjacent to theIc-ap, and means detaehably mounting said washer on plunger,- said washer having an opei'iing to permit the passage of said shaft.
